摘要

SARS-CoV-2新变体的免疫逃逸危及疫苗的有效性，需要新的免疫策略。在这里，我们评估了40名接受PHH-1V81 XBB.1.16-或BNT162b2 xbb .1.5适应疫苗增强剂的个体的抗体b细胞反应。两种免疫都显著增加了祖先反应性B细胞交叉识别疫苗变体。值得注意的是，XBB.1.16交叉反应性B细胞与中和反应相关，增强了PHH-1V81作为抗新变体的强大增强候选物的潜力。

Antibody and B-Cell Responses to PHH-1V81 XBB.1.16-Adapted SARS-CoV-2 Booster Vaccination Are Associated With Variant Neutralization

Immune escape by SARS-CoV-2 emerging variants jeopardizes vaccine effectiveness, necessitating new immunization strategies. Here, we assessed the antibody B-cell response in 40 individuals receiving either the PHH-1V81 XBB.1.16- or BNT162b2 XBB.1.5-adapted vaccine boosters. Both immunizations significantly increased ancestral-reactive B cells cross-recognizing the vaccine variant. Notably, XBB.1.16 cross-reactive B cells were associated with neutralizing responses, reinforcing the potential of PHH-1V81 as a strong boosting candidate against emerging variants.

期刊介绍： The Journal of Medical Virology focuses on publishing original scientific papers on both basic and applied research related to viruses that affect humans. The journal publishes reports covering a wide range of topics, including the characterization, diagnosis, epidemiology, immunology, and pathogenesis of human virus infections. It also includes studies on virus morphology, genetics, replication, and interactions with host cells. The intended readership of the journal includes virologists, microbiologists, immunologists, infectious disease specialists, diagnostic laboratory technologists, epidemiologists, hematologists, and cell biologists. The Journal of Medical Virology is indexed and abstracted in various databases, including Abstracts in Anthropology (Sage), CABI, AgBiotech News & Information, National Agricultural Library, Biological Abstracts, Embase, Global Health, Web of Science, Veterinary Bulletin, and others.
